The paper explores the defence by the early sociologist of science Ludwik Fleck against the charge of relativism. It is shown that there are crucial and hitherto unnoticed similarities between Fleck’s strategy and the attempt by his contemporary Karl Mannheim to distinguish between an incoherent relativism and a consistent relationism. Both authors seek to revise epistemology fundamentally by reinterpreting the concept of objectivity in two ways: as inner- and inter-style objectivity. The argument for the latter concept shows the genuine political background and intent of Fleck’s sociology of science and its ambition to relieve the cultural struggles of his time

Philip Kitcher’s account of scientific realism in 'The Advancement of Science' (AS) differs from his account in 'Science, Truth and Democracy' (STD). We demonstrate that (1) contrary to appearance, Kitcher in AS proposes a so-called Kantian realism that is accompanied not by a correspondence theory, but by a hybrid conception of truth. (2) Also, we point out that Kitcher does not pertain to the “promiscuous realism” proposed in STD stringently, but falls back on his Kantian realism of AS at points. Here, we question Kitcher’s claim that his promiscuous-realist conception stems initially from commonsensical be-liefs.

In two recent papers in Studies in History and Philosophy of Science Howard Sankey has argued that there is an intimate relationship between Pyrrhonian skepticism and recent approaches to epistemic relativism.Though the general argument and idea of Sankey’s papers is very much appreciated, it is argued that the epistemic relativist’s recourse to the skeptical strategy outlined by the Pyrrhonian is not a good one. This diagnosis gives rise to an objection against the epistemic relativist who argues on the basis of the skeptical strategy that differs from Sankey’s naturalistic response. Furthermore, it can be shown that what is really at stake between epistemic relativism and epistemic absolutism is the question of which criteria there are for variation of epistemic norms and epistemic systems.

In this paper, I show that there are important but hitherto unnoticed similarities between key figures of the Vienna Circle and early defenders of sociology of knowledge. The similarities regard their stance on potential implications of the study of science for political and societal issues. I argue that notably Otto Neurath and Karl Mannheim are concerned with proposing a genuine political philosophy of science that is remarkably different from today’s emerging interest in the relation between science and society in philosophy of science

The paper focuses on one central aspect of Karl Mannheim’s sociology of knowledge: his exemption of the contents of mathematics and the natural sciences from sociological investigations. After emphasizing the importance of Mannheim’s contribution and his exemption-thesis to the history and development of the field and the problem of relativism, I survey several interpretations of the thesis – especially those put forward by proponents of the so-called ‘Strong Programme’. I argue that these interpretations do not get the philosophical background and impetus of Mannheim’s contribution right. By distinguishing between naturalistic and anti-naturalistic strands in Mannheim’s work I propose a new reading on which Mannheim did not exempt the contents of the areas in question principally or because of a lack of nerve and will. It is argued that Mannheim’s exemption-thesis rather is a consequence of his own sketchy sociological investigations of ‘the paradigm of the natural sciences’.

In a reply to Howard Sankey I have maintained that the epistemic relativist cannot use the strategy of the sceptic since the relativist is at pains not to draw the sceptical solution. Sankey has objected to my argument by distinguishing between weak and strong justification: according to Sankey, the relativist using the sceptic’s strategy aims to provide an argument against the latter form of justification but still maintains that we can have the former.In this counter-response I argue that if this is really the relativist’s strategy then she cannot provide any argument against the absolutist at all. The reason is that she simply fails to address the key question in the debate about relative/absolute justification: are there any absolutely correct epistemic standards? The epistemic relativist using the sceptic’s strategy is thus trapped between the Scylla of undermining her right to maintain that there is relative justification and the Charybdis of providing no argument against absolutism at all.

Since Davidson's proposal to use a Tarskian theory of truth in order to develop a theory of meaning has been criticised extensively, it is decisive to ask whether Davidson needs such a theory as an assumption and premise in other parts of his work. Especially, many authors have claimed that Davidson's argument in his paper 'On the Very Idea of a Conceptual Scheme' depends on his approach in the theory of meaning. It is argued that this interpretation is wrong and Davidson's attack on conceptual relativism does not depend in any way on his defense of truth-conditional semantics. Rather Davidson's thoroughgoing holism and the principle of charity are the basic rationale for his denial of conceptual relativism.

The recently much discussed phenomenon of testimony as a social source of knowledge plays a crucial justificatory role in Richard Swinburne's philosophy of religion. Although Swinburne officially reduces his principle of testimony to the criterion of simplicity and, therefore, to a derivative epistemic source, we will show that simplicity does not play the crucial role in this epistemological context. We will argue that both Swinburne's philosophical ideas and his formulations allow for a fundamental epistemic principle of testimony, by showing that Swinburne has already implicitly justified the use of testimony as an epistemic source via his fundamental a priori principle of credulity.
